Yinyi®Drug-loaded coronary stent system without polymer micro-blind holes Product Description Yinyi® polymer-free microblind drug-loaded (paclitaxel) coronary stent (hereinafter referred to as "Yinyi® stent") is a new generation of drug stent independently developed and produced by Yinyi Biotechnology. The innovative drug delivery concept provides a safe, effective and economical treatment plan for patients with coronary artery stenosis. Features Traditional drug stents use high-molecular polymer carriers to carry drugs. With their widespread clinical use, many problems have been exposed, mainly as follows： ●Late stent thrombosis caused by delayed endothelial healing ●Late stage catch-up of restenosis caused by polymer chronic irritation and inflammation ●Acquired late adhesion ●Therefore, patients need to take long-term anticoagulant drugs to cause more bleeding risk The current effective means to solve these problems is to develop a new generation of polymer-free drug stents. The Yinyi® stent adopts an innovative drug loading concept, and uses a special treatment process to construct micro-scale blind holes to load paclitaxel on the metal surface, combining with the highly fat-soluble characteristics of paclitaxel. To achieve the best combination of drug release and the effect of inhibiting cell proliferation. Because there is no stimulating factor of high molecular polymer carrier, vascular endothelial cells are easier to cover the stent, Realize healthy endothelialization and shorten the time for patients to take anticoagulant drugs. Innovative microblind hole drug loading method Patented technology realizes micro-blind hole polymer-free drug loading
